WebMyresyre. Myresyre, også kaldet methansyre, er den mest simple alifatiske carboxylsyre og har konstitutionsformlen HCOOH. Myresyre kan fremstilles ved oxidation af formaldehyd ved tilstedeværelse af en stærk base. To formaldehydmolekyler reagerer med hinanden, hvorved der dannes methanol og anionen af myresyre.

Formic acid (from Latin formica 'ant'), systematically named methanoic acid, is the simplest carboxylic acid, and has the chemical formula HCOOH and structure H−C(=O)−O−H. It is an important intermediate in chemical synthesis and occurs naturally, most notably in some ants. Esters, salts and the anion derived from formic acid are called formates. Industrially, formic acid is produced from methanol.
